I

Myinvention relates to bearin gs for shafts orlz'lspindles revolving at high speeds, as in or inconnection with quick-running` motors or 1nachines,-ing which; bearings it is' necessary to provide for lateral movement to meet` l the eiiect arising from want of balance in` the rotating part.

To this end the invention comprises a bearing Vfor the shaft with yielding means for sup-y: porting and centering thesame and an auxil-` iaryensliilojning arrangement arranged to retardthej `lateral shifting of the bearing-` 1I willftillydescribenyinventicn with refer-f @n.06 t0.. th.

This is not necessary, `but only adinder E,1with another 'space Lzforrned in `the left ange c? and closedby a:ri ng e?, screwed nponthe "cylinder E. 1, Oilor other -liqiiidis supplied to this space I from a cup J (or other source) and flows to the space II and the bush -A by the orifices e4 e4 and e3, respectively. I prefer to X the inner flange or collar c2 of fthe cylinder E by screwing, as represented in Fig.' 1,` for in this ,way the adjustment for wearotthe 'ring Ghcan be conveniently effeqted-f The .Cyliildei E; "rthyts .rias ;G, is insertedfand retained in an` appropriately-- founded casing orother. convenient recessed `part Kg'inade of su eh` a diameterrin regard to the cylinder andring as to leave clearance around the forinerfbut be`iuftjght'fcontact withfthefringpin'which condition the ring is locked by screws g g, passed through the cas! ingor part K, "all as shown in Figs. 1 and 2.

'Theshape of the casing or part K is determined by the service. Two forms are eXe1nplied in the drawings, that shown in Figsg` 1 and 2 being suitable forxture to a bed-plate or otherbase, for which it is provided with a flange 7c, while the design illustrated inthe JindOSed wrath@ .Casing K b'ne :bolted at vthe end of thelnotorfgcasing bynjean Alugs irrr,-frrnlmh@ e n y @Imported by. radiell disposedfelasti' 9011-? `trivances LL;*each ituated Within"` a 'cavityqi` in the 'fcasingii isting Vof a springl,

illustrated in Fig."2,'from whine' IOO seen that the spring Z abuts upon the nut Z2 and a collar Z3 on the plunger Z', which rests upon the cylinder E through the bridge-piece Z4, resting upon a cut-away or flattened portion of the flanges e2 e2, and in this Way a good bearing is insured. The casing K and ring G are shown as recessed around these contrivances L L. This is for the purpose of permitting the reception of the bridge-piece Z4. By this construction and dispositionas the shaft or spindle B revolves friction is minimized by the balls C C, longitudinal motion is avoided by the fixture of the ring G, disposed on the cylinder E, and freedom to move transversely is permitted by the tof the ring G between the flanges e2 e2. The liquid held in the space H acts as a cushion to retard the movement of the bearihg. As the oil is forced out of one part of this space by this lateral movement of the bearing, due to the vibration of the shaft, some of it will be forced through lthe orifice e3 to the ball-bearings to lubricate the same.

The resilient devices L L tend to support and normally center the bearing.

Thus it Will be evident that by my invention I provide a very effective bearing for the particular use specified, and though I have only described and illustrated one form of it, because it is the one I find by experiment to meet my purpose Well, yet I Wish it understood that I do not limit myself to the exact details, as they are capable of various modi-V cation without departing from the principle of the bearing.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a bearing for shafts having vibratory movement, the combination with a shaft, of a bearing therefor, yielding devices for supporting and centering the bearin g and means for cushioning said bearing independent of said yielding devices.

2. The combination with a shaft having vibratory movement, of a bearing therefor, resilient devices for centering said shaft, and means for providing a liquid cushion for said bearing.

3. A bearing for shafts or spindles comprising the combination of a bush revolving upon antifriction-balls, an open-ended cylinder or sleeve encircling same and provided with external liauges, a ring establishing With the cylinder and flanges a space connecting with the bush and with another space in one of the anges, a casing in which the cylinder orsleeve and ring are inserted, and elastic contrivances in' the casing for supporting the cylinder, substantially as described.

In Witness whereof I have hereunto set my hand in the presence of tWo witnesses.

FREDERIC JAMES WARBURTON.
